Application of Geostatistics to Predict Earthquakes at Song Tranh 2 Hydropower Dam − Quang Nam

Abstract

    Earthquakes seriously affect human life and property. It can lead to epidemics, lack of basic needs, affect morale, ... The main goal of the author is earthquake forecasting to assess the risk of earthquakes in each region, shown in earthquake hazard zoning map, and compare with MSK seismic intensity scale to classify safe areas and hazardous areas. Based on the distribution of the accelerometer and the origin of earthquakes, applying the geostatistical theories, the study presents the process of choosing a suitable forecasting model for the data set and then produces a map that predicts the effects of earthquakes with high confidence. The results of the regression coefficient and the correlation coefficient are close to 1, the prediction error is close to 0. This study opens a new research direction on the application of Geostatistics to the fields related to geography such as earthquakes, mining, groundwater, environment, etc.
